My Charger's Hemi is making a ticking noise and I'm worried

Alright, so I need to get some opinions from people who actually know these cars because I'm starting to panic a little bit over here. I've got a 2018 Dodge Charger R/T with the 5.7 Hemi and I absolutely love everything about this car, the sound, the power, the way it just eats up the highway miles. But over the last couple of weeks, I've noticed this faint ticking noise coming from the engine, especially when it's cold in the morning. At first I thought maybe it was just the usual injector noise or something, but it seems to be getting a bit louder and now I'm starting to worry it might be the infamous Hemi tick that everyone talks about on the forums. I've read so many conflicting things online, some people say it's completely harmless and just a characteristic of these engines, while others say it's a sign of camshaft or lifter failure and if you ignore it, you're looking at a full engine rebuild. I took it to a general garage near my house and the guy just shrugged and said "it's a Hemi, they all do that" which didn't exactly fill me with confidence. I've been doing some research and I found a website, https://exoticautoservices.ae/dodge/dodge-repair-abu-dhabi/, that seems to specialise in American muscle cars and actually has proper diagnostic equipment to figure out what's really going on. I'm thinking of taking it there for a proper inspection but I wanted to see if anyone here has dealt with this ticking issue before and what the outcome was. Did you end up needing major work or was it something simple like an exhaust manifold leak? I really don't want to ignore it and end up with a catastrophic failure but I also don't want to throw thousands of dollars at a problem that might not even be serious. Any advice would be hugely appreciated because I'm losing sleep over this thing.
